For the past twenty years, I have poured my heart and soul into JRuby to bring new opportunities to the Ruby world. We built the first JIT compiler for Ruby, helped the community embrace parallel threads, and became the only alternative Ruby deployed at scale.

Today, JRuby continues to expand Ruby's horizons, offering unique features:

• Precompiling code for commercial products
• Single-file deployment with any JDK on any device (even mobile and embedded)
• Low-overhead profiling of production apps
• Simple, powerful multi-threading that uses all cores
• Cross-platform libraries for graphics, GUIs, games and AI

And with JRuby 10.1, we're adding new and amazing features and optimizations every day. You've never seen Ruby like this!

This talk will explore the history of JRuby and show how you can take Ruby to new places and open up a whole new world of Ruby applications.
